What this workflow does
This AI workflow has 22 nodes and runs on Gmail events. Along the way it connects Gmail, OpenAI Chat Model and Telegram. It also calls replace-tool-interlock-controller.example.internal over HTTP.
How it runs
Trigger: On Gmail events.
- Parse Particle Count Alert Email (Code): runs custom JavaScript code
- Normalize Excursion Record (Edit Fields (Set)): sets 4 fields: zone_id, tool_id, exceedance_ratio…
- Classify Excursion Severity (Basic LLM Chain): sends a prompt to an LLM, with model: Severity Classification Model
- Route By Cleanroom Zone Criticality (Switch): routes items into 3 branches
- Tag Protocol Tier Support Area (Edit Fields (Set)): sets 1 field: protocol_tier
- Tag Protocol Tier Process Bay (Edit Fields (Set)): sets 1 field: protocol_tier
- Tag Protocol Tier Litho EUV Bay (Edit Fields (Set)): sets 1 field: protocol_tier
- Combine Zone Tagged Records (Merge): merges the data from its input branches
- Route By Excursion Severity (Switch): routes items into 2 branches
- Log Minor Excursion (Data table): uses Data table
…plus 10 more steps. See the full node list below.
Services it uses
HTTP calls to: replace-tool-interlock-controller.example.internal
Before you upgrade to n8n 3.0
Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
- Still check Gmail Trigger below v1.4 runs as v1.4 (drafts skipped, max emails per poll) (Watch Particle Counter Alert Inbox).

Quick overview This workflow monitors a Gmail inbox for cleanroom particle-counter excursion alerts, parses the email into structured measurements, uses OpenAI to classify severity, routes by zone criticality, and either logs minor events or runs an…
